Hi, I have a textfield on a form. I would like that the textfield to only accepts numbers.When submit button is presseed it takes to another page called test.php.
I want that if the user enters anything other than numbers,it doesn't go to test.php but stays on the same form and tells the user to enter only numbers. Can this be done in php?
Here's the code which I am trying but isn't working.Thanks
CODE


<label>Start Number:
  <input name="number" type="text" />
  <?PHP
  
    $number = $_POST['number'];
    function text_and_spaces_only($number)
    {
    return preg_match('/[0-9 ]+/i',$number);
     }
  
?>

  </label>

Thanks for the help. How command can I use to remain on the same form and not go to the other page called test.php if the user does not enters numbers.
